When the furnace starts making that loud banging noise at 2 AM, you know it's not going to fix itself. I had to call a repair guy last winter because the pilot light kept going out, and he found a cracked heat exchanger that could've leaked carbon monoxide. He replaced the igniter and cleaned the burners, and now it runs quieter than it has in years. It's one of those things you don't think about until the house gets freezing cold.
